Cold temperatures can affect everything from a car’s battery to its tire pressure, so proper maintenance this time of year can greatly decrease the chances of your vehicle letting you down.
AAA Carolinas has seen an increase in battery-related service calls since Tuesday and expects that trend to continue if the forecast calls for overnight temperatures below freezing.
Following is a simple checklist to determine a vehicle’s fall and winter maintenance needs. Many of the items can be inspected by a car owner in less than an hour, but others should be performed by a certified technician.
•Battery and charging system — Have your battery and charging system tested by a trained technician. A fully charged battery in good condition is required to start an engine in cold weather. When the temperature is below freezing, a battery only generates 60 percent of its current charge.
•Tire type and tread — In areas with heavy winter weather, installing snow tires on all four wheels will provide the best winter traction. All-season tires work well in light-to-moderate snow conditions provided they have adequate tread depth. Replace any tire that has less than 3/32-inches of tread.
•Tire pressure — Check tire inflation pressure on all four tires and the spare more frequently in fall and winter. As the average temperature drops, so will the pressure in tires — typically by one PSI for every 10 degrees Fahrenheit. Incorrect tire pressure can reduce a vehicle’s fuel economy by 3-4 percent. Proper tire pressure levels can be found in the owner’s manual or on a sticker typically located on the inside of the driver’s side door. Tire pressure should be checked when tires are cold.
•Lights — Visibility is important, especially when it starts getting darker earlier. Check the operation of all headlights, taillights, brake lights, turn signals, emergency flashers and back-up lights.
•Wiper blades — The blades should completely clear the glass with each swipe. Replace any blade that leaves streaks or misses spots. In areas with snow, consider installing winter wiper blades that wrap the blade frame in a rubber boot to reduce ice and snow buildup, which can prevent good contact between the blade and the glass.
•Washer fluid — Fill the windshield washer fluid reservoir with a winter cleaning solution that has antifreeze components to prevent it from freezing.
•Transmission, brake and power steering fluids — Check all fluids to ensure they are at or above the minimum safe levels.
